The attacker videos seemly were mostly about exercising, vegan diet, and some lighthearted videos...
AFTER demonetization, seemly some videos with criticism about Youtube and US, saying that Iran (her home country) had more free speech than US, showed up.
At the risk of drumming up unneeded controversy, it reminds me of when Marine Le Pen in France tweeted graphic images from ISIS actions as a rallying cry against them, only to be charged by the state with circulating violent content inciting terrorism ( https://www.theguardian.com/world/2018/mar/01/marine-le-pen-... ). Without proper application of context and judgment, a terrorist spreading propaganda and an anti-terrorist illustrating the terrorist's propaganda would be seen as the same sort of thing.
Of course, there's no simple solution -- we wouldn't want a world in which someone could get out of responsibility for spreading needlessly graphic content just by saying "oh I was just spreading it for educational purposes!".
Can automated processes ever hope to achieve the nuance we need in our societies?
Well, it's not exactly that: it was a response to a comment from a journalist, which could be interpreted as equating the Front National (MLP's party) to ISIS.
